Some researchers have suggested that natural gas appliances are significant contributors to indoor air pollution. Indoor unvented combustion appliances, such as gas-fired ranges, unvented space heaters, and portable kerosene space heaters, have been associated with a wide variety of pollutants, including carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO{sub 2}), sulfur dioxide (SO{sub 2}), formaldehyde (HCHO), and respirable particles. Previous indoor air quality studies have demonstrated that indoor NO{sub 2} concentrations often exceed outdoor ambient levels when gas- burning appliances are used. Cooking with gas has been the focus of many of these studies, although other unvented appliances, such as space-heaters, have also been associated with elevated NO{sub 2} concentrations. Some epidemiologic studies of exposure to NO{sub 2} in homes with gas ranges have indicated a higher prevalence of respiratory symptoms and illness. However, other studies contradicted these findings and failed to show any significant effects associated with gas cooking.
